It's 1962 and change is in the air in Baltimore. Tracy Turnblad, a girl with big hair and big dreams, has only one passion in life - to dance on "The Corny Collins Show." When her chance arrives, she grooves her way into instant stardom and the eyes of teen-dream Link Larkin (Zac Efron). But with the program's scheming stage manager (Michelle Pfeiffer) against her, trend-setting Tracy will need the help of her best friend Penny (Amanda Bynes), her bighearted mother (John Travolta) and sassy co-host Motormouth Maybelle (Queen Latifah) to show the world that all it takes to make a dream come true is a toe-tappin' beat and a little "Hairspray!".
